weblogic7+jbuiler7初学者bean互相调用问题求教（在线求教）

[u_u_u]

我的环境是weblogic7+jbuiler7，调用的次序如下：
client->session bean->entity bean->db
问题处在session bean->entity bean环节，
主体代码如下（省略了系统自动生成的代码，编译发布成功）：

import cmpdemo.*;

public class HelloBean2Bean implements SessionBean {
public java.lang.String SayHello()
{
try
{
Tab01 tab = getTab01Home().findByPrimaryKey("abcdefg");
return new String(tab.getName());
}
catch(Exception e) { throw new EJBException(e); }
}

private Context getInitialContext() throws Exception {
String url = "t3://localhost:7001";
String user = null;
String password = null;
Properties properties = null;
try {
properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put(Context.PROVIDER_URL, url);
if (user != null) {
properties.put(Context.SECURITY_PRINCIPAL, user);
properties.put(Context.SECURITY_CREDENTIALS, password == null ? "" : password);
}

return new InitialContext(properties);
}
catch(Exception e) {
throw e;
}
}

private Tab01Home getTab01Home()
{
InitialContext initCtx = null;
try
{
Context ctx = getInitialContext();
Object ref = ctx.lookup("Tab01");
return (Tab01Home)ref;
}
catch(Exception e) { throw new EJBException( e); }
}
}

客户端代码为自动生成代码执行时出错（entity bean Tab01单独用自动生成客户端测试没有问题），信息如下：
